“…In addition, every subject in the cohort reported good comfort and dryness with SLs, and their subjective ratings were comparable with ratings of soft contact lens wear. 18,19 Therefore, we conclude that post-lens tear mixing is slow during scleral lens wear, as the changes of bulbar and limbal redness, and corneal staining and average comfort score after 5-hour scleral lens wear, were comparable with published data for soft contact lens wear. 20,21 This finding may be different with other lens designs and especially in the light of the emergent trend of customizing the scleral lens fit with toric peripheries.…”

“…In order to establish whether CLD is a function of the time of day at which lenses are worn, Papas et al assessed comfort in a group of participants without lens wear over an 8-h period and showed that this stayed reasonably constant throughout the observation period. 76 When participants were fitted with contact lenses for 12 h, after the first few hours, comfort scores reduced significantly, in a fashion typical of that commonly expressed by contact lens wearers. When participants were asked to wear the contact lenses for 4-h periods starting in the morning, in the afternoon, or late afternoon, a characteristic pattern resulted, regardless of the starting point.…”

The number of contact lens wearers worldwide has remained relatively stable over the past decade, despite the investment that has gone into contact lens technology. This is largely because 10%–50% of wearers dropout of contact lens wear within 3 years of commencement; the most common reason cited being contact lens discomfort (CLD). Of the symptoms reported, sensation of dry eye is the most common. Given the outcome of reduced wearing time, increased chair time, and ultimate contact lens discontinuation, the challenge is to identify the warning signs of CLD early on. Clinically detectable changes such as conjunctival staining, conjunctival indentation, conjunctival epithelial flap formation, lid wiper epitheliopathy, Demodex blepharitis, and meibomian gland dysfunction have been linked to CLD, highlighting the need to perform regular aftercare visits to identify these changes. At a cellular level, conjunctival metaplasia and reduced goblet cell density have been linked to CLD, leading to a downstream effect on the tear film breakup time of contact lens wearers. These factors suggest a strong link between CLD and friction, raising the need to target this as a means of minimizing CLD. The purpose of this review is to identify the clinical signs that relate to CLD as a means of earlier detection and management in order to combat contact lens dropout.

“…Thus, analyzing the safety and comfort of silicone hydrogel SCL it can be noted that the probability of DES development is considered against the background of their use in the majority of researches [8,9]. However, the dynamic research of the clinical picture of the dry eye having developed after systematic use of SCL according to clinical recommendations is undoubtedly important [13]. A topical issue is the comprehensive assessment of functional parameters reflecting lacrimation and tear film stability during the development of pathological process.…”

The probability of dry eye syndrome (DES) in the patients using the Silicone-Hydrogel Contact Lenses is examined in many researches. Therefore, adhering to clinical recommendations is an important factor for DES prevention. The urgent issue is also a comprehensive assessment of functional parameters as pathogenetic base of DES.The objective of the research was tostudy DES development depending on compliance of silicone hydrogel contact lenses users.Matherials and methods. 97 patients (194 eyes) were included into the research. They formed 2 groups: group I with incomplete compliance (36 persons) and group II with complete compliance (61 persons). All the patients underwent the Norn’s test, Schirmer’s test, Jones test, tear film stability was defined. The probability of the dry eye syndrome development due to the subjective signs was also analysed.Results. The reliable decrease in the total (р<0.05) and basale lacrimation (р<0.05) indexes, the increase in osmolarity (р<0.05) and decrease in tear film stability (р<0.05) were detected in the patients who did not follow the clinical guidance during the Silicone-Hydrogel Contact Lenses wearing. In the same group the higher risk of dry eye syndrome development was verified (р<0.05).Conclusion. Compliance disorder in the patients using Silicone-Hydrogel Contact Lenses was found to induce the reliable decrease in total and basale lacrimation, increase in osmolarity and tear stability disorder. All of this factors increase the risk of dry eye syndrome.
